“…A number of current media browsers employ simultaneous presentation of data in addition to size zooming techniques for browsing of photographs (e.g., PhotoMesa [Bederson 2001]), music (e.g., SonicBrowser [Fernström and Brazil 2001] and SoundTorch [Heise et al 2009]), or even visual content of videos (e.g., [BlinkX]). These browsers employ size as a visual feature enhancing saliency (bigger visual objects are more salient).…”

Situated in the context of multimedia browsing, this study concerns perceptual processes involved in searching for an audiovisual object displayed among several distractors. The aim of the study is to increase the perceptual saliency of the target in order to enhance the search process. As blurring distractors and maintaining the target sharp has proved to be a great facilitator of visual search, we propose combining visual blur with an audio blur analogue to improve multimodal search. Three perceptual experiments were performed in which participants had to retrieve an audiovisual object from a set of six competing stimuli. The first two experiments explored the effect of blur level on unimodal search tasks. A third experiment investigated the influence of an audio and visual modality combination with both modalities cued on an audiovisual search task. Results showed that both visual and audio blurs render stimuli distractors less prominent and thus helped users focus on a sharp target more easily. Performances were also faster and more accurate in the bimodal condition than in either unimodal search task, auditory or visual. Our work suggests that audio and audiovisual interfaces dedicated to multimedia search could benefit from different uses of blur on presentation strategies.

“…In [139], synthesis parameter selection was evaluated using a range of low-level audio features, such as Fundamental Frequency, Spectral Shape, Envelope Characteristics, and Overall Duration. They also used the discrete cosine transform of the Mel-Frequency Cepstral Coefficients as a measure of how similar the synthesized sound was to a recorded sample.…”

Procedural audio may be defined as real-time sound generation according to programmatic rules and live input. It is often considered a subset of sound synthesis and is especially applicable to nonlinear media, such as video games, virtual reality experiences and interactive audiovisual installations. However, there is resistance to widespread adoption of procedural audio because there is little awareness of the state of the art, including the diversity of sounds that may be generated, the controllability of procedural audio models, and the quality of the sounds that it produces. The authors address all of these aspects in this review paper, while attempting a largescale categorization of sounds that have been approached through procedural audio techniques. The role of recent advancements in neural audio synthesis, its current implementations, and potential future applications in the field are also discussed. Review materials are available * .

“…Thus, using the concept of information sharing in a biological society to provides opportunities for the particles in a group to communicate with each other and exchange information in the search for a more effective solution for finding the system optimization parameters. In recent years, PSO has been widely used in acoustics including automatic adjustment of off-the-shelf reverberation effects [39], comparison of optimization methods for compression driver design [40], optimization of micro-perforated sound absorber [41], and optimization of acoustic filters [42].…”

In this work, microspeaker frequency response was determined based on measurement and simulation. The vents after the rear chamber of the microspeaker were covered with ventilation cloths. Two types of ventilation cloths (acoustic cloths) are commonly used in electroacoustic products, non-woven and woven. Non-woven cloths (5 nos.) consist of irregular meshes and woven cloths (5 nos.) consist of regular meshes. The equivalent circuit model of the microspeaker was formulated by considering five types each of non-woven and woven ventilation cloths. The acoustic properties of the ventilation cloths were estimated from the measured frequency response of the microspeaker and by subsequent use of particle swarm optimization algorithm. Estimated value of the acoustic impedances of the ventilation cloths were used in an equivalent circuit model of the microspeaker for the simulated frequency responses and subsequently compared with the anechoic chamber measurements. Based on the results, the equivalent circuit adequately simulated the measured frequency response of the microspeaker and the estimations of the acoustic impedances of the ventilation cloths were in good agreement with the measured frequency responses of the microspeaker.
